Etymology. The specific epithet is a patronymic given in honor of the Spanish singer Alejandro Sanz, who has greatly contributed to Spanish music.

Diagnosis. Males of Macrophyes sanzi n. sp., resemble those of M. elongata Chickering, 1937 by the conical ventral tegular process and a retrolateral tibial apophysis with a small posterior projection (see Brescovit 1992, figs 6, 7), but can be distinguished by the quadrangular, straight retrolateral tibial apophysis and wider ventral tegular process ( Figs 1 View FIGURE C−E). Females are similar to those of M. elongata by having an oval atrium, differing mainly by their rounded and large spermathecae. Also, resembles to M. pacoti Brescovit et al., 2019 by the large and rounded spermathecae, separating by the shape of the atrium ( Figs 1F, G View FIGURE ).

Description. Male. (Holotype, MPUJ_ENT 0061936). Carapace yellowish dark in the cephalic region. Chelicerae brown, labium and endites brown. Sternum yellowish-brown.

Palp: retrolateral tibial apophysis small and apically straight, with a small projection on posterior side; cymbium shorter than tibia; subtegulum longer than wide; tegulum longer than wide, with ventral tegular projection wide, laminar; median apophysis long, curved, apically inserted on the tegulum; embolus short, apically filiform, with narrow base and proximally inserted on the tegulum ( Figs 1 View FIGURE C–E).
